The Benedict solution contain copper(II) sulfate which is blue.
The Benedict solution is used to test mono- and disaccharides.
The white powder that turns orange in Benedict's solution is glucose. Benedict's reagent contains copper ions which can be reduced by glucose, resulting in a color change from blue to orange-red.
A base/alkali substance will turn litmus paper blue.
take blue litmus paper put it in the solution if it turns red its acidic if it remains blue its either basic or neutral to test if its basic put red litmus paper in the solution if it turns blue then its basic if it remains red then its neutral . it is only applicable in solutions.
Starch is likely present in the solution if iodine turns blue-black. This color change is a characteristic reaction that indicates the presence of starch.
Dip the litmus paper into the solution in question. If the paper turns red, the substance is acidic. If the paper turns blue, the substance is basic. If there is no color change, then the substance is neutral.
Because this solution contain copper(II) sulfate.
It helps in indicating whether a substance is acidic or basic A red litmus paper turns blue in basic solution and turns red in acidic solution A blue litmus paper turns red in acidic solution and turns darker blue in basic solution

Dip the litmus paper into the solution in question. If the paper turns red, the substance is acidic. If the paper turns blue, the substance is basic. If there is no color change, then the substance is neutral.
If iodine solution turns blue-black, it indicates the presence of starch. Iodine forms a complex with starch, resulting in the blue-black color.
A substance that turns blue litmus paper to red is acidic. This indicates that the substance has a pH value below 7. When the blue litmus paper comes in contact with an acidic solution, it changes color to red due to the acidic nature of the solution.
Starch is present. Check a potato with iodine.
